This is a life saver and has repaired my hair which in turn helped it from breakage. I will not go without this product EVER ### ⭐⭐⭐⭐⭐ Hair Breakage Has Stopped *by S***Q on April 17, 2023* I use and love Olaplex. Then, I discovered K18. After using K18 shampoo and leave-in treatment for a month, my hair has stopped breaking or falling out. Even my daughter mentioned it. I still use Olaplex at least once a month (especially when coloring hair), and I use K18 shampoo and leave-in treatment at least 3 times a week. Love all of these products, especially since I hilight my hair ever 6 - 8 weeks. ### ⭐⭐⭐⭐ Definitely helps hair feel softer, though have to use a lot *by R***M on December 28, 2023* My stylist used this on me, and I had to have it! Great for when you don't have time to fully condition or just to add a little extra softness. I did find the recommended amount to be to little. It says start with 3 pumps. I have just past my shoulders, but with shaved sides; so a lot less than most people with long hair. I have to use at least 9 pumps to get full coverage. This means it gets used as way faster, which equates to making it more expensive per usage. Great product of you don't mind the expense. ## Frequently Bought Together - K18 Leave-In Repair Hair Mask, 4-Minute Speed Treatment, Renews Hair Damage From Color, Chemical Services Heat (1 of each 50ml & 15ml). - K18 PEPTIDE PREP™ Color-Safe Detox Clarifying Shampoo, Non-Stripping, pH-Optimized Cleanse, Removes Product Buildup, Dirt, Oils & Metals, 8.5 Fl Oz --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/409093018-k18-leave-in-repair-hair-mask-4-minute-speed-treatment](https://www.desertcart.us/products/409093018-k18-leave-in-repair-hair-mask-4-minute-speed-treatment) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-28*
